Silica Gel desiccant

Silica gel is a solid and organic stirring material that is synthetically made from sodium silicate and it is an amorphous form of silicon dioxide, which is produced in the form od beaded (having presence of small spherical) and granular (hard irregular appearance of crystals) with having a high surface area that makes silica gel a highest capacity of moisture adsorption capacity than other adsorbents.

Silica Gel Packets

The water molecules adhere to the surface area of silica gels because it exhibits a lower vapor pressure than the surrounding air. Once the saturation level is reached of equivalent pressure, no more adsorption process ensues. Thus the greater amount of humidity condition (above 50% relative humidity) and water portion that is adsorbed before steadiness is grasped.

Silica gel is using for different applications. Its usage is increasing day by day. In the future, as per the research analysis, within 5 years the market of silica gel and silica products will have a huge hype. In the food industries, packaging industries, glass industries, machinery, electronic industries...the area of its application is really high.

Desiccant is another name of silica gel. as said before, the application area of silica gel is wide. Therefore, for each industrial application desiccant is available in different names sometimes with little differences.

For example, if you are running a glass industry you can use normal white desiccant for your applications. If it is the food industry or drug industry, definitely you will be worried about the hygiene of food and pharma products. But the manufactures made it clear. That is considering Clariant turkey company, they are manufacturing all the types of absorbing products for all the applications.

Their, Oxy-guard desiccant is mainly focussing on food and pharma industries. Container Dri desiccant is mainly focussing on packaging and shipping industries. Normal silica gel can be used for all applications.

Desiccants and Silica Gel

Desiccants are always considering as a perfect partner to keep along with for moisture-sensitive products. In the pharmaceutical industry, the most commonly used desiccating materials are silica gel, molecular sieves, and clay minerals. They can be incorporated into sachets, canisters, cards, or maybe into bottle closures.

Like excipients, these desiccants show humidity-dependent sorption/desorption behavior. However, their sorption capacity is far above typical excipients. This allows them to perform effectively in a much lower amount relative to drug products.

The overall moisture absorption capability of the desiccants are often calculated from the weighted sum of the moisture sorption isotherms of the active pharmaceutical ingredient (API), excipients, and desiccant. Use of desiccant isn't advised in cases where high levels of unbound water should be maintained for product performance (e.g., gelatin capsule shells).

We all are familiar with small silica gel packets. In our daily life, we are meeting those tiny packets from many places such as along with our new pair of shoes, inside our laptop bag, in a tablet container, along with the pregnancy kit, ...etc.

Usually, we will not keep these tiny silica gel packets once we opened the shoebox or laptop bags. But once we are familiar with the advantages of silica gel, we will never throw it. It has a good capability to absorb moisture from the surroundings. That is why the manufacturers are keeping it with their new products to avoid damages due to excess moisture.

We can use silica gel packets along with our food items also. There is a specific product named oxy-guard, which can keep along with the food products. Oxy-guard is an oxygen absorber. It can absorb oxygen from the food items such as bread, coffee beans, dried nuts, ...etc and keep them fresh for a long time.

Silica Gel for flower drying

Silica gel is a desiccant. It has a lot of uses in our daily life. It can be used for preparing homemade dried flowers. Dry flowers have a good scope in the decoration and event management industries. The best is always fresh flowers. However, if we need to extend our decorations for a long time, dry flowers are the best option.

Some kind of desiccants can be used to dry flowers. Silica gel is one of them. Let's see how we can dry flowers in our home by using silica gel. We can use flowers from our garden or fresh flowers from our nearest grocery. Put the silica gel into an airtight container avoid exposing to the atmosphere.

We know that silica gel desiccant is non-toxic and inactive. However, we recommend wearing a mask, and using gloves are better when handling this kind of stuff. When you pour the silica gel into the container, it can produce a very fine dust. That is not good to inhale.

To start the process of drying flowers, add a layer of silica gel crystals about 1.5 inches thick into your container. Then put the flowers in the container and pour more crystals in and around the petals until fully covered but not submerged completely. Seal the lid closed when done, and set the container in a dry place.

Usually, it will take only 2 to 4 days to dry it completely. Silica gel is a good moisture absorber. But make sure it is not exposed to the atmosphere. Because if it is exposed to the atmosphere, there is a big chance to get hydrated so soon.

In the atmosphere the presence of water is very high, silica gel can absorb it easily and become hydrated easily. But another thing is we can regenerate it by using a simple oven. By reheating the silica gel by using an oven for 20 minutes at high temperatures it can regain the capacity to absorb moisture quickly.

Silica Gel Desiccant

Silica gel is a desiccant. Above all the desiccant packets we can see the writings "Do not eat". And we know that silica gel desiccant is an inactive substance, that will not act with any other chemicals or substances. Then why it is indicating do not eat and keep out of children?

Usually, nothing happens if you eat any desiccant as we know. But it can make many discomforts to the person who eats it. Silica gel is using a drying agent. It can remove humidity from a closed area. Silica gel is non-toxic so that it is not poisonous if eaten but here is some side effect if u ate silica gel by chance:

• Dry eyes - Because silica gel can absorb water content from the surroundings.

• An irritated, dry feeling in your throat

• Aggravated, dry mucous membranes and nasal cavity

• An upset stomach or stomach discomfort

Silica desiccant is added to improve flow in powdered foods. It naturally occurs in water, where it may help develop resistance against developing senility. Actually, silicon dioxide is the real name of silica, and that is the main component of sand.

As we know silica gel is non-toxic, non-flammable, and chemically inactive. However, some of the granules may be combined with a moisture indicator, such as cobalt (II) chloride, it is carcinogenic. It can give color to the gel. Cobalt chloride is deep blue, that is the reason for blue colored silica gel when dry (anhydrous) and pink when moist (hydrated).

This is the reason for silica gel packets are labeled as dangerous or poisonous when eaten or "Do not eat". Silica gel is safe, it does not cause silicosis. But crystalline silica dust can cause silicosis. Generally, silica gel is assuming as a non-dangerous substance because of these reasons, however, keep it out of your children.

silica gel is a desiccant. It is manufacturing from some chemicals such as sodium silicate. Like sodium hydroxide, Sodium silicate is a strong base. Silica gel normally appears in the shape of spheres. these small granules have a lot of advantages in our daily life.

As a desiccant, it can be used for absorbing excess moisture from any products or from any closed surroundings. sodium silicate is a chemical substance, the recommendation is to not induce vomiting, because of its corrosive nature. While you see a tiny packet of silica gel, always you can see the writings "do not eat"on it.

By accident, if you consumed silica gel, nothing serious but irritations might be there. If enough sodium silicate begins absorbing water from the lining of your mouth and esophagus, you will experience a soapy sensation and begin to feel burning. Because of the alkaline nature of the sodium silicate, it will start to eat away at your skin. It is even more hazardous if the dust gets in your eyes.

Silica gel is prepared from sodium silicate by the method of acidifying sodium it, and would not be expected to be alkaline- it is silicon dioxide (same as sand). Even if it were I would expect any remaining alkaline nature is potentially neutralized as soon as it hits your stomach.

If it is completely neutralized, there would not be the soapy sensation and there's just a risk of irritating as it goes down if it absorbs water from your mucosal lining and scratches them up. If the desiccant is dissolved in a glass of water, one could measure the pH to determine the risk of burns and would render this risk minimal to non-existent in my book.

That said, a couple of grams in a silica gel packet would not constitute a hazard severe enough that I personally would rush off to the hospital if I accidentally swallowed one. It mentioned DO NOT EAT visibly on it, and you should NOT EAT. I repeat, just because something has a negligible risk of poisoning you does not mean you can "try" eating it.

Silica Gel Dubai

Most silica gel packets contain one or two grams only. Silica gel desiccants are considered "hazardous" because of its potentially irritating nature, not because of its toxicity. Sodium silicate is listed to have an LD50 of about 1.6g/kg. Silicon dioxide is listed to have an LD50 of >~5g/kg, more than 3x times less poisonous than sodium silicate.

If the silica gel in the packet is blue (turns pink), it is doped with cobalt chloride, which is typically used in desiccants such as Drierite at about a 3% level. There are claimed non-toxic (orange) alternatives, but the indicator within the orange silica gel is, if I'm reading things right, either Methyl Violet (turns purple) or ferric ammonium sulfate (turns clear/ lt purple/blue-green).

Cobalt chloride LD50 = 766 mg/kg. So at 3% of the silica, it's no more toxic than the silica gel itself, proportionately, as long because it isn't more than about 10% approximately of the silica. Cobalt compounds are supposed to not be bioavailable, precipitating in physiological

concentrations of phosphate and binding strongly to albumin. However, oral administration of 80mg/kg of cobalt chloride was shown to induce chromosomal changes in mice http://oem.bmj.com/content/58/10/619.abstract, so if the silica gel was blue or pink, I'd probably be very worried if I ate some, even though I wouldn't expect to feel anything.

Methyl Violet LD50 = 413mg/kg. More toxic than CoCl2! Again, in proportion, less toxicity risk than the silica gel itself, as long because it isn't more than 5% of the silica. Ferric Ammonium Sulfate is pretty much nontoxic, so I would expect this is the form used in the packets included with food.

As a desiccant, it can be used to absorb moisture from the surroundings. Commercially, it is using worldwide as a moisture absorber. It can contain a wide range of "ingredients". Silica gel is manufactured from some chemical combinations such as sodium silicate, acidified to silicon dioxide/silicic acid.

Silica Gel desiccant

Silica gel is a desiccant. As we know, all these desiccants are used to absorb excess moisture from the surroundings. It is one of the most commonly used products to avoid moisture damage. We can see small packets of silica gel in our daily life along with some of our daily use items such as laptop bags, some kind of medicines, ...etc.

Based on the types of applications, desiccants are available in different types. For example, to avoid container rain and cargo damages during transportation, container desiccants are available. To avoid moisture from dried food products to keep the items fresh, food protection desiccants are available. Similarly, various types of desiccants are available in the market.

We can see the writings "Do not eat" on every packet of desiccants or silica gel. Do you think is there any problem when you have it? We know that desiccants are non-toxic, inactive, and odorless. Then why it is mentioning like that with high importance. Because whatever it is, the consumption of silica gel is not good.

Unless we eat dozens of silica gel packets, nothing important. Silica gel usually comes in those little packets that are marked ‘Do Not Eat’ to remind people as it is not intended to eat. They are normally with products that would not benefit from having excess moisture in them. The silica gel itself absorbs about 40 percent of its weight in moisture and brings down the humidity of the surrounding container as well.

So, how dangerous is it really? Silica gel is nearly harmless, as it is an inert element, meaning we could find it in food products such as dried fruits and nuts, coffee beans, or along with some kind of medicines and some medical products such as pregnancy test kit, ...etc.  If you tried to eat one packet of silica gel, here’s what would happen.

As soon as you empty the packet into your mouth, all the moisture would be sucked away from the sides of your mouth and your tongue, giving you a very dry feeling. Assuming you didn’t immediately spit out the silica gel, you’d suffer from a myriad of symptoms, such as dry eyes, throat, membranes, and an upset stomach.

Most people know about silica gel, that we are not supposed to eat it. It is the unseen substance that inhabits those tiny white packets placed in new shoe boxes, laptop bags, and Asian snack foods, or with some medicines. It will keep the product safe by absorbing excess moisture from the surroundings.

Invariably, the ominous warning “do not eat” is always there above the silica gel or desiccant packet. Sometimes it is mentioned by the edict, “throw away.” In case that’s not clear enough, a few varieties depict a skull and crossbones. It is generally a substance which is not acting with any other products or chemicals. Let's see what happens if you eat it?

Nothing, nothing will happen if we eat any desiccant as a small quantity accidentally. And we know that we will not eat a big quantity by accident. Silica gel is another form of silicon dioxide, it is a naturally occurring mineral, better known in its granular form as sand or in crystals as quartz. Its most important feature is its porousness, which permits it to absorb up to 40 percent of its weight in water.

In the middle of the 20th century, it has been started widely used as a desiccant, placed inside containers to avoid the contents from getting damp. Most commonly, it comes in the shape of beads packed in a permeable packet. It can easily absorb wet contents from the surroundings of products, but make sure it is a closed container. 

Silica gels are used in everything from museum display cases to electronic equipment packaging. It can be used directly along with food products also. Because as it is a non-toxic element it will not make any changes to the food products.

We can describe silica gel as an inert, non-toxic substance that’s essentially harmless.  It is Indigestible. Because when it passes through the body and comes out looking much the same as when it went in, we can say that it is indigestible.

Silica Gel - FAS Arabia

Silica gel and desiccants are familiar to everyone. We can see tiny packets of silica gel while we are purchasing new shoes or laptops. Inside the laptop bag or shoebox, the packaging companies are putting small packets of silica gel to absorb excess moisture from the closed surroundings.

One thing we need to make sure while putting silica gel with any products to absorb excess moisture, it must be in a closed container or packaging. Because, until a certain limit only silica gel can absorb moisture. Therefore if it is not in a closed container it will try to absorb water molecules from the atmosphere also. So the limit will reach soon. Then again we need to change it.

Silica gel is additionally combined with alkali metals to make an M-SG reducer. Considering the above properties of silica gel researchers are inclined to use silica gel. In developed countries, a vast expansion of technology has bought sophisticated instruments for purifications of chemical mixtures involving silica gel.

But developing and poor countries not in a position to afford such expensive instrumentation are adapted to the techniques involving usage of silica gel manually. Due to the amorphous nature of silica, it easily enters into the respiratory system of Humans and causes a lot of effects. Inhaling silica dust can cause silicosis, bronchitis, or cancer, because the finely divided dust becomes lodged within the lungs and continuously irritates them, reducing lung capacities.

Studies of workers with exposure to crystalline silica desiccants have shown 10-fold higher than expected rates of lupus and other systemic autoimmune diseases compared to expected rates in the general population. So this shows that even this inactive chemical agent can make health issues to humans while inhaling for a long time.

Desiccants are normally considering as an inactive substance. However, having it or inhaling it for a long time can make significant issues to human beings. Researches are showing the result as it should be considered properly while handling every day.

Silica Gel - Clariant

Silica gel is one of the most important products which is used worldwide for the absorption of moisture from its surroundings. They are tiny granules and having a porous structure. This makes the silica gel more capable to absorb more water content into its body.

They are well popular among industrial people. They have a high level of usages. Many industries are using silica gel world wide. One of the main manufacturers of silica gel is Clariant. Clariant is a well-established company which is producing different types of moisture-absorbing solutions.

The Clariant company is situated in Turkey. They are mining natural bentonite clay from their home country. It is directly sending to their well-established factory to produce different types of high-quality desiccants and moisture-absorbing solutions. They are not adding any chemical content to the clay. By natural process only they are producing all the products.

Clariant is producing different types of moisture-absorbing solutions such as Container Dri, Oxyguard, Desi Pak...etc. Each product is using for different purposes. They are keeping their standards and quality in each of their product. All these desiccants are the alternate of silica gel.

Container Dri is manufactured mainly for absorbing moisture from cargo to avoid damage loss while transporting something important by ship. There is a big chance for condensation and climate change during shipping time and traveling time. Therefore the wet will make damages the things. By placing Container Dri we can avoid it it is the best desiccant.

Oxyguard is mainly used for protecting pharmaceutical products and food products. They are harmless and inactive. They will not make any changes by reacting with the food items. It can be directly used with food containers. Because it is safe. It is good moisture absorbing desiccant. By removing water content it will help to keep the food product for a long time as fresh.

Benefits of silica gel

Benefits of Silica Gel 

What Are Silica Gel Packets?

Silica gel is a desiccant that can absorb moisture content from its surroundings. It is popular in the market, because of the ability to absorb moisture and water content from the atmosphere it can protect products from the damages due to excess water content.

There is a lot of products on the market that can be damaged due to moisture presence. It will make a big loss to the production companies as well as to the transportation companies. Therefore desiccants become the most popular product in between them. In all the desiccants, silica gel desiccant is the most common one.

Silica gel is easily available on the market worldwide. It is not reactive with any other chemicals, oils, acids, or any type of substance. It is considering as an inactive agent with other things. Therefore we can handle it easily as well as we can dispose of it with normal disposals.

Desiccants are one of the best and cost-effective for companies to protect their products from excess water content or damages.  We can see small silica gel packets along with some products which need dry packaging such as shoes, laptops, some medicines...etc.

To avoid the spoilage of many products we can keep silica gel packets along with it. It will not harm us because of its inactive character. The products such as electronics, vitamins, medical products such as pregnancy tester devices, leather goods, dried meat products, dried nuts and fruits, bread products, and more.

Once you got silica gel packets along with any products, do not throw it. Because it has many other benefits apart from industrial uses. In our daily life we can use these tiny packets for several applications such as to remove water content from our mobile screen, to avoid spoilage of coffee powder, to protect pregnancy test kit from moisture...etc.

Silica Gel Suppliers in Dubai

Silica Gel Suppliers

Nowadays silica gel is an important factor to protect electronics, medical products, machinery, containers...etc. Therefore the need for silica gel is increased. In this situation, many companies and factories started to produce silica gel by using different methods.

Silica gel is having a good market value. also, consumers need a high quantity of silica gel. Therefore nowadays silica gel and its other products having a good demand on the market. It has an expiry time also. Therefore we should change it time by time. Therefore the need for silica gel is an endless process. Silica gel suppliers in UAE is a large list, but you can approach a good supplier all the time. Choose the best quality product even if it is a small quantity.

I have mentioned about silica gel expiry time, actually, it is not like that. Silica gel has the capability to absorb moisture and wet from the atmosphere as well as from the outer surface of the products and materials. So once it absorbed the wet from the atmosphere, and reached to its maximum, then they can not absorb any more. At that time, we have to change it.

Desiccant

Desiccant is another form of silica gel. Nowadays silica gel is available in different forms like a desiccant, container Dri, oxy-guard...etc. Actually, all these products are the various form of silica gel produced by Turkey company Clariant.

Depends on the application companies are producing a different form of silica gel. Like Clariant manufactures, there are some other companies producing silica with different names. Desiccant is mainly used for protecting electronics and machinery. It is highly required by big industries who are having big electrical and mechanical machinery.

All over the world day by day, the requirement for silica products is increasing. Therefore there are a lot of manufacturers and suppliers available in this field. The best silica gel and desiccant suppliers in UAE are FAS Arabia LLC Dubai.

Silica disposal

Silica Desiccant

The synthetic amorphous silica gel is an inert without any known negative effect on the environment. Therefore the disposal process of silica gel is clearly normal. That makes more easy for the users. They can dispose of it with the normal wastes.

Silica gel is not classified as a hazardous material under EEC directive 91/689/EEC. Therefore using and disposal of it is easy. Normally silica gel is used to absorb water and moisture from the atmosphere. Its porous structure will help to do it. It can contain more water than the weight of it.

Up to a certain limit, silica gel is absorbing moisture. Normally it is not absorption. it is an adsorption process. After reaching the limit, it will lose the capability to adsorb water. So it will become a waste. But fortunately, there is an option to reuse it. We can reactivate silica gel by using an oven for reuse.

Silica gel is a desiccant. It has various forms. Many of the companies are producing a different form of silica gel for different applications. Therefore we are getting more results. For example, if the application is cargo and shipping, we have to go with Container Dri. It is specially designed for cargo and shipping by Clariant UK.

If our application is food product protection, We have to choose the desiccant with a different character. For food products, need more protection and safety. It should not be harmful to food items. So we have to choose Oxy-Guard for that.

Similarly, if the application is medical products or electronic, semiconductors, machinery, we have to choose different desiccant forms. We have to choose the best quality silica products always to protect all the items.

Silica gel is not classified as special waste under UK special waste regulations 1996 and can be disposed of with normal waste. It will be helpful for users. All the forms of silica can be disposed like this.

Silica Gel Applications

Silica Gel Applications

Silica gel is commonly used as an absorbing agent all over the world. It can be available in different forms for different applications. The purpose is the same for all the application, but sometimes the behavior of the application is different like food products, electronics items, machinery...etc. So by considering different application behavior, different form of silica gel is available on the market.

The main applications of silica gel moisture absorber are drying and cleaning of air and gases, drying of analytical samples, drying of solvents, drying of synthesis products, optical instruments, and devices, protection of export consignments from moisture in a salty atmosphere, drying and storage of flowers and seeds.

A desiccant is another form of silica gel. Desiccant is also used as a moisture absorber. It is porous particles. It can absorb a high amount of moisture from the atmosphere as well as from the surroundings of the other products. Therefore it is widely using in industrial applications as a good absorbing agent.

Desiccants are mainly used in the gas industry, dehydration, and purification in Oxygen, Hydrogen, and Chlorine, In the steel refinery industry and oxygen plant, it can be used to remove ethane from oxygen. Etc. Silica Gel is also used in the Dehumidifier. Desiccant Dehumidifier white silica gel is used. Silica Gel is also used in the Analysis of Chemicals.

Silica gel can be used to protect a lot of items from moisture. It can be used in Toolboxes, Storage containers, Safes, and vaults, Silver drawer, Firearms, Photos, Stored vehicles, Cargo hold on RVs, boats, etc, Collectibles (stamps, coins, etc.), Computer, Medical equipment, Leather products, Textiles, Seeds, and jewelry items.

Desiccants are also used in Metal and machine parts, Industrial equipment, Pharmaceuticals and vitamins, Electronics, Military instruments, Circuit Boards, Documents, Instruments, Photographic equipment and film, Foodstuffs, Batteries, Pet foods, and Optical devices.

Silica Gel Definition

Silica Gel Definition

Silica gel is an amorphous kind of silicon oxide, that is synthetically created within the form of hard irregular granules (having the looks of crystals) or hard regular beads. A microporous structure of interlocking cavities offers an awfully high surface area (800 sq. meters per gram).

It is this structure that produces silica gel a high capability drier. Water molecules adhere to the desiccant's surface because it exhibits a lower vapor pressure than the surrounding air. When the equilibrium of equal pressure is reached, no more adsorption occurs. Thus the higher the humidness of the encircling air, the greater the amount of water that is adsorbed before equilibrium is reached.

It is in these higher humidness conditions (above 500th Relative Humidity) that hold on or in-transit things are liable to damage. The beauty of silica gel is that the physical adsorption of vapor into its internal pores.

There is no chemical process, no by-products or side effects. Even once saturated with vapor, silica gel still has the appearance of a dry product, its shape unchanged. Silica Gel is one of the oldest and most popular desiccants and adsorbent used for a wide number of industrial and consumer applications.

Silica Gel may be an extremely activated adsorbent, furnished in a wide range of mesh sizes to suit various industrial applications. It is non-corrosive, odorless, tasteless, non-toxic, and chemicals inert. It is an extremely porous kind of oxide, with an extremely large internal surface area.

The desiccants do not undergo any chemical reaction during adsorption and do not form any by-products. It is non-deliquescent and can not modify its size or form. Even once the colloid is water-saturated, it remains dry and free-flowing. We can re-use these silica gel once they reached their maximum absorption level by re-heating it in an oven. But for industrial uses, it is not possible to re-heat a high volume of silica gels.
